"The centre’s employees need to build more performance and customer interaction skills", it concluded.

When The National visited Emirates Post in Karama on Monday, only three of the seven service counters had staff present, at the busiest part of the day, with 15 people waiting in line at one desk.

Some staff also appeared willing to serve customers who had jumped the queue.

Omar Mohammed, 26, from Pakistan, said the process in service centres is often drawn out and inefficient.

"Person to person transactions are still difficult across many services," he said.

"It is much easier to do your business online, if you can, because the standard of service from people on the other side of the counter is so inconsistent," he said, adding most retailers and government centres have improved.

“You used to have to rely on machines in shops, to pay your bills, and there was always some issue with them,” he said.

Thomas Biesewig criticised broader postal delivery services, saying: "During my time in UAE only 50% of my mail has arrived and then with a delay of weeks or months. Christmas cards arrived a week before Easter."

Other users said offering more part time jobs - which are relatively rare due to the way the visa system works - would help the public and private sectors to better handle busy periods of the day.

Sheikh Mohammed has previously pledged to improve efficiency in public service.
